`^ VEHICLE-TIRE,

Specification of Letters Patent,

Patented Apr. 11, 1911.

Applioationled September 27, 1910. Serial No. 584,042.

To alt whom fit may concern:

Be it known that I, JOI-1N G. Fnnnha citizen of ythe United States, and residing n1 thc borough of Swissvale, in the county of Allegheny and State of Pennsylvania, have invented -or discovered new and useful 11nprovements in Vehicle-Tires, of which the following is a specification.

My invention consists in a new-and 1mproved tire for automobiles and other vehicles.

, Generally speaking the tire consists of an inner rim removably attached to the felly of the Wheel, a pneumatic tire of novel con struction removably mounted on said inner rim, an outer ri-:n removably mounted on sa-idpneumatic tire, and a tread portion secured to the outer surface of said outer rim. Novel construction is shown in the attachment of the inner riin to thefelly and of the various 'parts of the tire structure to one another. I provide the outer rim with a series of laterally extending studs or projecf tions which by contact prevent skidding, add to the. tractive effect and assist in crossing y or mounting car-tracks and other irregularities in the path of the vehicle,

In the accompanying drawings, Figure l is a vertical section of the felly of a Wheel provided with my vimproved tire; Fig. Z is a segment of the same in side elevation, and Fig.' 3 is a broken view similar to Fig. l but showing a modification of the tread.

The following is a detailed description of the drawings.

l represents one of the spokes of'a vehicle Wheel and 2 the folly. 3 is a metal rimmounted on said felly and secured thereto by means .to be described.. The edges ofthe rim 3 are turned up to form clenchers 1-4.

5 is a shoe or 4casin of a pneumatictire which may be made ov the material usually employed for that purpose,A such as vulcanized fiber. The shoe 5 is inclosed having an annular opening or slot 6 in its inner Wall for the .introduction of the inner tube and. the attachment of the shoe to theinner rim.

The lateral edges Aof the inner face of the tire are formed as annular lips 7 7 which engage the clenchers 4&4: of the rim 3. The shoe is removably secured in place on rim 3 by means of a series of-bolts 8 Whose round' ed headsengage the interior Walls of the shoe 5 and Whose Shanks extend through the slot 6 in said shoe and also through registering holes in the rim 3 and the telly 2, By

Wardly to form' a. channel or seat 12 for the tread7 and then laterally and inwardly to formtseats 134-13 for the lips 10-10 of the shoe. 5.

14p represents one of a. series of set screws Whose heads are contained in countersunk Washers 15 in the interior ofthe shoe 5 and which extend through the Wall of shoe 5 and engage threaded` holes in the Web of rim ll.

It is evident that the outer rim may be readily detached from the shoe 5 When desired.

i6 is the inner tube, seated in shoe 5 and adapted to be inilated in the usual manner.

1.7*17 represent a seriesof projections on the outer rim ll which serve to engage the roadway in soft or n'iuddy 4places and prevent slriddin'g und 'increase the tractive force. They also assist'the wheel in climbing obstructions and in' turning in or out of car tracks.

The outer tread, carried by outer rim 1l.,

composedl of: cushion base 1S. preferably made up of folded or layer fabric vuloanized` together, and a tread portion proper which may be constructed in various man` ners. In Fig. l I have shown the same consisting of ring of copper or other metah 19, seated in channel l2, and ysuperimposed on cushion 18, while in Fig. 3 I have shown thetread portion proper composed of solid rubber attached to the cushion. Among the metals l prefer copper its softness 'and ductilit)Y adds to its tractive power and seats it more firmly in the channel l2. Its use'is attended with but very little noise compared to steel or iron treads.

lt will. be observed that not lonly may my tire structure be readily assembled together I and as readily dis-assembled, but that the structure as a Whole may' bc readily removed fromgthe wheel and another tire structure substituted with as little delay and trouble as attends the ren'ioval of the shoe of an ofthe tube 16 no accident Will result as .my

tire structure will not wholly collapse, as would an` ordinary pneumatic tire but the .wheel may be used as before Without danger of accident or injury to the tire.

It is evident that the inner rim which I have illustrated is substa'tntially identical to the usual forni of cleneher rim in ordinary "use, so that my pneumatic tire, outer rim and tread may be mounted as a Whole upon the rim of an ordinary vehicle wheel.

What I desire to claim is:- l. In a vehicle tire, the combination of an inner rim detaehably attaehable to the elly, an inelosed shoe provided with an an nularopening .along its inner periphery,

j saidshoe having a flat outer face with annularradial projections along its lateral edges, an outer rim adapted to be mounted on. said fiat face and havinglr annular seats for said radial projections, and 'a tread secured to said outer rim, substantially as described.

2. In a vehicle tire, the combination of an inner rini detaohably attachableto the ifelly7 an inelosed shoe, of flattened triangular cross-section and having a Hat outer face provided with annular radial projections along' its lateral edges, mounted on Said inner riln, an outer rim. adapted to be mounted ou said tlatvface and having annular seats for said radial projections, screws extending` through the Wall of said shoe and engagingY threaded holes in said outei` rim, v -and an outer tread mounted on sald outer rim, substantially described.
